Going too far

Sometimes when I read the newspaper, I wonder what parents want from their children's school systems. Certainly there can be differences of opinions pertaining to assignments like the slavery assignment in the Caldwell school system. But why is it necessary to further stoke the controversy by continuing to express dissatisfaction even after the assignment is canceled? Administrators have a tough enough time evaluating curriculum to see if it meets state standards. After the controversial lesson is withdrawn, another one must be selected in its place. Don't public school superintendents have enough responsibility without being concerned about a parent who has her way on her original request but makes further demands? Sometimes a simple comment such as "Thank you for listening to my point of view and taking the time to make adjustments" is the best response.
